Expand description
Describes one of the subpasses of a render pass.
Restrictions
All these restrictions are checked when the RenderPass
object is created.
TODO: that’s not the case ^
- The number of color attachments must be less than the limit of the physical device.
- All the attachments in
color_attachments
anddepth_stencil
must have the same samples count. - If any attachment is used as both an input attachment and a color or depth/stencil attachment, then each use must use the same layout.
- Elements of
preserve_attachments
must not be used in any of the other members. - If
resolve_attachments
is not empty, then all the resolve attachments must be attachments with 1 sample and all the color attachments must have more than 1 sample. - If
resolve_attachments
is not empty, all the resolve attachments must have the same format as the color attachments. - If the first use of an attachment in this renderpass is as an input attachment and the
attachment is not also used as a color or depth/stencil attachment in the same subpass,
then the loading operation must not be
Clear
.
Fields
color_attachments: Vec<(usize, ImageLayout)>
Indices and layouts of attachments to use as color attachments.
depth_stencil: Option<(usize, ImageLayout)>
Index and layout of the attachment to use as depth-stencil attachment.
input_attachments: Vec<(usize, ImageLayout)>
Indices and layouts of attachments to use as input attachments.
resolve_attachments: Vec<(usize, ImageLayout)>
If not empty, each color attachment will be resolved into each corresponding entry of this list.
If this value is not empty, it must be the same length as color_attachments
.
preserve_attachments: Vec<usize>
Indices of attachments that will be preserved during this pass.
